Technical details
Endpoint
GEThttps://api.400860.xyz/v1/design/agent-handoff-packWhen to prefer
Choose this endpoint when you need a pre-packaged, structured operational guide specifically for transitioning design artifacts and context into an AI agent or MCP-compatible workflow. It is best suited for teams or agents that need a standardized handoff protocol rather than building one from scratch.
Side effects
- Payment not completed — endpoint requires x402 micropayment of $0.01 USDC before content is returned
- Invalid query parameters may result in a 400 error
- Service unavailable or timeout if the upstream provider is down
- Missing required 'input' object with type 'http' and method 'GET' in request body may cause validation failure
